Abstract: ABSTRACT OF THE DISCLOSURE      Surface coating methods and apparatus are disclosed which eliminate many of the disadvantages associated with known coating processes from pollution, equipment, materials, energy, labor and cost standpoints.  According to techniques described, liquid compositions containing film-forming solids are formulated, then conveyed in the foam state towards a surface, and upon foam disintegration, form a film of solids on the surface.  The tech-niques disclosed eliminate the need for solvents in paints or reduce volatile content to very minimal amounts.  This method also enables polymeric compositions having high molecular weight to be employed as coating materials.  Furthermore, the method has utility in nearly all coating processes where the film-forming solids are conveyed from a bulk state to a surface for coating.

Abstract: A. FISCHER - 1 (Revision) Abstract RF the Disclosure An RF power amplifier with a pulse modulating facility is disclosed in which a pre-emphasized pulse modulating signal is derived from a plurality of amplitude values stored in a memory.  The stored values are continuously changed by a control signal to give the output signal of the amplifier the desired shape.  This compensates for nonlinearities and aging effects.  The time required for the modulated carrier wave to pass through the amplifier need not be considered because the envelope comparison between the amplifier output signal and the required modulating signal, which generates the control signal, is independent of the time of occurrence of the amplifier output signal.

Abstract: The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with vacuum jacket, depend from opposite sides of an elongated manifold.  The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferable of metal or glass in U-tube configurations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes. The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space.  Solar energy collected on the absorber surface of the inner glass tube wall is transmitted to the U-tube and liquid therein.  The U-tube within the collectors is blackened and non-reflecting.  Principal heat transfer from absorber to U-tube is by radiation with some conduction and convection transfer.  The heat transfer liquid is entirely within a closed circuit, which avoids leaks, reduces weight, and cycle time of the liquid is reduced to a fraction of other liquid systems. The manifold and tubes are fastened to a support structure of novel construction enabling fabrication as a module and mounting on a solar exposure of a structure such as a roof, wall or frame.  Several modules are interconnectable to desired capacity for a particular solar powered heating or cooling system.
